Captive-bred Aquarium Form

Overview

Several generations of captive breeding have produced individuals better adapted to harder water and a wider range of parameters compared to wild specimens.

Appearance

Shared with the species: Spanner Barb

The body is elongated and moderately compressed, brownish-silver with a metallic sheen. Two characteristic broad black markings stand out on the flanks: a vertical bar near the caudal peduncle and a horizontal stripe extending forward from it, forming the T-pattern. Juveniles show 3–5 dark spots along the midlateral line. Males develop dark head tubercles during spawning condition. A large species — adults reach 15–18 cm in length.

Care

Shared with the species: Spanner Barb

A spacious aquarium of at least 300 liters and minimum 150 cm length is required. Powerful filtration and moderate flow are necessary. Optimal water parameters: temperature 20–28°C, pH 6.0–8.0, hardness 1–10 dGH. Furnish with rocks, driftwood, and robust plants attached to decorations (Microsorum, Anubias). Weekly 30% water changes are mandatory. Juveniles are social; adults can be territorial — sufficient space is essential.

Feeding

Shared with the species: Spanner Barb

Omnivorous fish that accept a wide range of foods. Quality flakes and pellets form the staple diet. Live and frozen foods — bloodworms, artemia, daphnia, tubifex — are eagerly consumed. A plant component is mandatory: spinach, lettuce, zucchini, spirulina-based foods. In the wild they forage on algae, detritus, crustaceans, and insects.

Compatibility

Shared with the species: Spanner Barb

A boisterous species that may intimidate or harass less robust tankmates, especially small or slow-moving fish. Best tankmates include large danios, other medium and large barbs, big loaches, small cichlids, and similarly tempered species. Not suitable for community tanks with veiltail, small, or delicate species. Juveniles school together; adults may become more solitary.

Breeding

Shared with the species: Spanner Barb

Home breeding is possible and occurs periodically without special effort. Use a spacious breeding tank with 10–15 cm of water, a fine gravel substrate, and dense planting of fine-leaved plants. Condition breeders separately for 1–2 weeks with live foods. Spawning at 26–29°C; the pair actively pursues each other. Remove adults immediately after eggs appear. Incubation is 24–36 hours; fry become free-swimming after 3–4 days, initially feeding on infusoria then artemia nauplii.

Fun facts

Shared with the species: Spanner Barb

The name 'Spanner Barb' comes from the English word 'spanner' (wrench): the T-shaped pattern resembles the silhouette of an adjustable wrench. The species can reach 18 cm in length — making it one of the largest aquarium barb species, which necessitates a very spacious tank. Juveniles actively school together, while adults often prefer their own territory — this behavioral shift makes the species particularly interesting to observe over its lifespan.
